Help ID LED Bulb

I have been swapping out all my bulbs for LEDs. I got quite a few cheap 921s from ebay which worked out fine but a bit too bright for my kids in their bunks. I did a bit of research and found that you want to stay about 5000k with color and maybe 12 led lights, so I ordered a few more of those types to try out and got these. They are the wrong ones for sure but wondering if anyone knows more about them. The seller is refunding me the money and I have 10 of these now. I have yet to try them out in the trailer just in case they are not the right LED at all I don't want any issues. They have a stamp on it that says 241 but nothing else, google search comes up with nothing.

The ones I got:

    I agree; plug one in and see. It might very well work for you, although I'd wager that it is alot brighter than you are looking for.
  • Why not install one and see what it does? It's not going to hurt anything.
  • I was trying to identify the bulb in my hand, they sent the wrong one and wondering if I can use these as well. The 2 links you sent those are the exact ones I wanted but got the one in the photo instead.

    I'm not sure I understand your question. You are asking us to identify an LED bulb (the one in your picture) that YOU bought? What were they described as when you bought them?

    You say they are "the wrong ones for sure"...why? Do they not plug in at all (the base looks similar to a 921)? Do they plug in but not light up (LEDs are polarity dependent; you did try rotating them 180 degrees, right?)? Are they simply too bright or too dim?

    Again, I'm not sure what info you are asking for? If you want 921 (wedge) base also known as T-10, but not too bright,
    Try these
    Or these

    Back in the day when this craze first started the magic word was WARM WHITE. Back then the concept was replace the incandescent HOT bulbs with small LED boards...

    I got these from ebay china for $4.99 each or 10 for $45.00

    They are still working in my ceiling fixtures...




    All of the american made were very expensive and most often included the built-in regulator circuit that would cause RFI interference with HDTV TV signals, WX RADIO signals, and HAM RADIO signals etc... If you some installed now go to OTA TV and see hows your work with your HDTV. Mine HDTV would blank off and then time out to the BLUE SCREEN. Turn off the lights and it would jump back to working again... IT was worse when using the OTA Antenna which probably has a weaker signal than coming in from the CABLE TV hookup...

    This is the COMMAND ELECTRONICs LED BOARDS I purchase a bunch of which interfered with my Radio Electronics. You can see the REGULAR parts mounted close to the cable connections... I gave all of these away...



    There were only a few companies back then that actually made a direct replacement for the incandescent bulbs... This is in the 2008 2009 time era...

    The trick for me after loosing my shirt haha was to just buy one and try it out first then buy 10 or 20 of them...

    Being a big time OFF-ROAD CAMPER replacing the Incandescent bulbs for LEDs is a must thing to do.. The only down side for us was the Incandescent Bulbs did give off alot of heat and that actually helped in the cool nights... When I removed the fixtures to install the LED BOARDs everyone of the ceilings was scorched behind the fixtures from too much heat being generated. Kinda scary to me not knowing this...
